Caption: Pilot flying a Concorde. Pilot's hand operating the thrust levers of a Concorde supersonic aeroplane. These levers control the engines, which provide the thrust necessary for takeoff, cruising and landing. The panel behind the thrust levers contains dials and instruments used by the pilot during a flight. Four columns of dials (left) correspond to each of the four engines. To the right are instruments that display speed and altitude information.
